Scope of Application
chatlyn GmbH, Renngasse 4/R4-4, 1010 Vienna (hereinafter "chatlyn") operates a service platform for centralizing and automating communication between companies as providers and private individuals as requesters, as well as enhancing marketing activities.
These General Terms and Conditions govern the use of the platform software and related services provided by chatlyn.
Subject Matter of the Contract
chatlyn provides registered users with internet access to software as a Software-as-a-Service offering. Users must maintain their own internet access and can remotely access hosted servers.
Services include software provision, user rights granting, user data storage, and agreed support services. The specific scope, contract duration, and fees are determined in individual offers accepted by users either through sales employees or independent website booking.
Platform use depends on user connections to third-party communication services. chatlyn has no control over these services' extent or conditions, and changes or cessations do not reduce chatlyn's payment claims.
WhatsApp integration occurs through the WhatsApp Business API, provided to users through a service partner arrangement.
Conclusion of the Contract
Contracts may be concluded personally with chatlyn employees or independently via the website.
Employees send proposals to potential users, who accept by signing and returning documentation. Website-based contract conclusion requires selecting a service package, providing information on Stripe's payment processor site, and clicking confirmation to conclude the contract.
Registration and Use of the Platform
Only registered users may access the platform. Users either self-register via website or are registered by chatlyn post-contract, receiving an administrative account.
Registered users may create employee accounts with specified names and email addresses, setting individual permissions per agreement. Accounts enable platform use within agreed service scope.
Account data must remain current, complete, and accurate. Changes require immediate user account updates or chatlyn employee communication.
Only authorized persons may use customer and employee accounts. Users are responsible for access data confidentiality and must not share credentials. Misuse or credential loss must be immediately reported to chatlyn.
Users bear responsibility for all account activities, including linked employee accounts.
Availability of the Platform
chatlyn strives to provide the platform with utmost care and availability, though uninterrupted availability is not guaranteed.
chatlyn may temporarily restrict platform access or functionality for maintenance or feature provision, with at least one week advance notice for availability-affecting work.
Users must immediately report platform errors or disruptions outside their control to enable troubleshooting.
User Rights
chatlyn grants non-exclusive, non-transferable rights to use software within agreed scope and period per these Terms and Conditions, limited to agreed user numbers.
Users may not reproduce software, make it available to third parties except for intended use, or rent, lend, distribute, or otherwise provide it remuneratively or gratuitously.
Users may not develop similar products using the software and must refrain from reverse engineering, decompilation, and other impermissible actions.
Support
chatlyn provides user support services within individually agreed scope. Additional services beyond statutory obligations require separate payment, with fees communicated before commissioning.
User Obligations
Users commit to lawful platform use and must not distribute content violating applicable law or harming third parties. Platform use affecting availability or security is prohibited.
chatlyn does not check user content and customer communication for legality. Users bear responsibility for data protection regulation compliance and connected third-party system terms. If third-party system access becomes restricted due to user behavior, chatlyn bears no liability and retains full payment claims.
Users must provide necessary hardware and software to use chatlyn's platform and configure IT systems appropriately. Related support services are provided by chatlyn for fees unless covered by individual agreements.
Compensation
Fee amounts derive from individual offers or contracts. Annual subscriptions require advance full-year payment upon invoice receipt; monthly subscriptions require monthly payment. Invoices specify payment deadlines and are sent electronically.
Offered discounts and benefits apply only to initially booked periods. Discount and benefit granting is entirely chatlyn's discretion, with no legal claim to further granting after original contract expiration. This applies to contract extensions or new contracts intended to obtain special conditions.
Contract Duration and Termination
chatlyn offers monthly and annual subscriptions as specified in individual contracts or offers.
Monthly subscriptions are concluded indefinitely and terminable monthly by either party with 30 days notice.
Annual subscriptions carry one-year minimum duration unless individually agreed otherwise. Either party may terminate at minimum period end with 90 days notice. Unterminated contracts extend another year, again terminable with 90 days notice.
Serious contractual obligation breaches entitle either party to terminate without notice for important reasons. Important reasons for chatlyn include two-month payment default or significant fee arrears, user insolvency, or over-indebtedness.
Terminations require written communication via email or mail.
After contract expiration, active user and employee accounts are deactivated or deleted, preventing further platform use.
Data Protection and Confidentiality
chatlyn processes user data necessary for contractual relationships per the Data Protection Declaration for Users provided at or before contract conclusion.
User customer data processing occurs solely on user behalf — chatlyn acts as data processor per Article 28 GDPR. chatlyn concludes separate data processing agreements meeting GDPR requirements as necessary.
chatlyn treats all user-accessible contractual information confidentially. Disclosure to employees and service providers occurs only when necessary for contractual fulfillment and with confidentiality obligations.
Users must treat chatlyn business and trade secrets disclosed during contract execution confidentially and not disclose or otherwise use them.
Reference Attribution
chatlyn may use user names and logos plus provided services for marketing, including demonstrations and advertising in press releases, websites, presentations, trade fairs, seminars, exhibitions, and comparable occasions.
Liability, Compensation, and Warranty
chatlyn's liability, to legally permissible extents, covers only damages from gross negligence or intent. Financial loss liability is excluded, including employee and legal representative liability.
Austrian General Civil Code warranty provisions apply. chatlyn does not guarantee platform or software complete availability and error-free operation. No defect exists for insignificant or temporary functionality restrictions or defects arising from user control.
Changes to the Terms and Conditions
Terms and Conditions modifications must be written.
chatlyn may change these Terms if unforeseeable changes, particularly technical or legal, necessitate revision, including provider term-of-use changes or use restrictions. Primary performance obligation changes, such as fees, are excluded.
Written change notifications go to users via email. Changes are deemed accepted if users don't object within two weeks. Objecting users receive extraordinary termination rights with two-week notice, provided notification referenced consent fiction and termination rights.
Final Provisions
These Terms and Conditions and all agreements between chatlyn and users are governed by Austrian law. UN Convention on Contracts for International Sale of Goods application is excluded.
Exclusive jurisdiction for disputes arising from these Terms and individual contracts is Vienna, Austria, unless mandatory statutory provisions apply otherwise.
